Electro-optic dual-comb vibrometry
We use an ultrafast electro-optic dual comb interferometer to perform single-point vibrometry on the submillisecond time scale. As an example, we resolve the vibration of an ultrasound speaker driven at 50 kHz, achieving a sub-nanometer axial resolution through a measurement of the optical phase carrier.

متن کاملElectro-optic dual-comb interferometer for high-speed vibrometry.
Electro-optic frequency comb generators are particularly promising for dual-comb spectroscopy. They provide a high degree of mutual coherence between the combs without resorting to complex feedback stabilization mechanisms. In addition, electro-optic frequency combs can operate at very high repetition rates, thus providing very fast acquisition speeds. Here, we exploit these two features to res...
متن کاملElectro-optic dual-comb interferometry over 40 nm bandwidth.
Dual-comb interferometry is a measurement technique that uses two laser frequency combs to retrieve complex spectra in a line-by-line basis. This technique can be implemented with electro-optic frequency combs, offering intrinsic mutual coherence, high acquisition speed and flexible repetition-rate operation. A challenge with the operation of this kind of frequency comb in dual-comb interferome...
متن کاملHigh Speed Electro-Optic Modulator with Comb Like p-i-n Diode
We propose an electro-optic modulator with a comb like diode structure. By placing the doped regions into the minima of the standing wave inside the resonator, modulation bandwidth is increased with low additional losses.
متن کاملTunable Comb-Channels with Orthogonal Polarizations Based on Coupled Resonators and Electro-Optic Effect
We designed a coupled resonator structure and studied its transmission properties through the tightbinding approach and the transfer matrix method. Based on the coupling of resonant modes and the electro-optic effect, some comb-channels with two orthogonal polarizations can be obtained. The total number of channels is two times the number of resonators. The orthogonal polarization channels cann...
